The Lowdown

G’day, Rusty here. Looking at the full 16-day stretch for Jaconé, it’s a bit of a mixed bag. We’ve got a slow start, a couple of proper days, and then a lot of onshore junk. The water’s sitting around 72°, which is pretty much average for this time of year, so no surprises there. Let’s get into it.

The first few days are basically a write-off. Sunday the 30th is all cross-onshore breeze and tiny, choppy waves – nothing to paddle out for. The swell energy is weak, around 129 and fading. Monday the 31st is glassy but tiny, only about 2ft of east swell. It’s surfable but very ordinary, so don’t hold your breath.

Then there’s a gap. Tuesday the 1st and Wednesday the 2nd are blown out with onshore winds and messy seas. The energy picks up Tuesday morning, hitting 486, but it’s all wind-swell junk with the wind howling straight onshore. Not worth the drive.

Now, here’s the first real standout. Thursday morning the 3rd of September looks proper. The wind goes glassy, and we’ve got about 5ft of south swell with a 10-second period. That’s a solid pulse, the combined energy is a strong 528, and the conditions look clean and lined up. This is the first day you’d genuinely want to be in the water. The afternoon goes cross-offshore but still holds around 5ft, so it’s still workable, just not as epic.

Friday the 4th is also a good one. The swell drops a touch to around 4ft, but the period stretches to 11 seconds, giving it some real push. Light offshore north-east winds in the morning will have it clean and hollow. The energy is still solid at 368. This is your second standout – a proper groundswell pulse with favorable winds. Saturday the 5th is back to nothing, onshore slop and tiny waves.

The following week is more of a lottery. There’s a bigger pulse around Monday the 7th of September – about 7ft of south swell with a 10-second period and cross-offshore winds. The energy is pumping at 924, but it’s a bit raw and the winds aren’t perfect. It’s promising, but I’d call it more for the experienced crew. The rest of that week fades into onshore winds and mush. A few small windows of clean conditions pop up, like Friday the 11th afternoon and Saturday the 12th morning, but the swell is inconsistent and nothing special.

So, bottom line: the best surfing in this window is Thursday the 3rd and Friday the 4th of September. Thursday has the size and clean conditions; Friday has the longer period and offshore winds. Everything else is either too small, blown out, or messy. Plan around those two days.

Rusty out.

Information about the Jaconé Surf forecast

The above surf forecast table for Jaconé provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Jaconé can be found by selecting the local surf guide option on the grey menu. Our Jaconé surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Jaconé) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).

Further information to help with frequently asked questions about our surf forecast for Jaconé may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
